Get answers you can count on with the new Asphalt Annualized Lifecycle Calculator

 

Two important factors come into play in the design of any asphalt mix: Initial Cost and the Projected Years of Life. Engineers, contractors and pavers all wrestle with decisions on which mix will yield the longest pavement life for the best value in dollars spent. To aid in this endeavor, engineers use an equivalent annualized cost approach called Life Cycle Cost Analysis (LCCA), to aid in the decision.

Phil Blankenship, P.E., has combined his years of experience in the asphalt industry with a wide range of documented results from studies of asphalt pavement to create the Asphalt Annualized Lifecycle Calculator, an online tool that can help determine both lifespan and payoff time frames.

“Tools like this are important to use, because they can evaluate various mixes and lengths of time to see how they compare,” said Blankenship, an independent industry consultant who also serves on the Surface Tech Advisory Committee.

One critical feature of the new calculator is its ability to compute results in terms of today’s dollars (net present value), an important capability to evaluate the time value of the pavement investment . The calculator allows a user to compare  several mixtures and combine each with various additives to see how the estimated value of the mixture will compare in cost to a standard.. The current estimated life of US pavement surfaces averages about nine years before needing replacement. Additionally, the calculator takes into account the salvage value of the pavement to produce results that compare equally across various mix designs in terms of cost.

“The objective for this calculator was to achieve an apples-to-apples comparison,” said Blankenship.

With construction costs rising, it becomes ever more critical to seek out new ways to predict return on investment (ROI). This new calculator shows you what can happen when you test various mixes against their projected lifespans. In short, it’s a try-before-you-buy tool that can save you both money and buy you time.

A custom asphalt mix design utilizing ACE XP polymer fibers has given a general aviation airport the long-term solution it sought for a nagging pavement cracking problem. Initial results show the custom design, which combined both a binder layer and a surface layer reinforced with ACE XP, will exceed expectations by greatly reducing cracking potential.

The six-year-old runway pavement at Taylor County Airport in Kentucky was failing. Airport authorities called on Palmer Engineering to provide a desperately needed 15-year-plus solution to the pavement’s micro-cracking problem. Working with Haydon Materials, the team turned to an expert with long-standing experience in designing crack-resistant asphalt pavements.

“The airport authorities were concerned that numerous cracks in the existing pavement could lead to failure, a common failure in airport pavements as aging occurs can create FOD — Flying Object Debris — causing a danger to the aircraft and potentially the traveling public.”

No milling was done on the runway pavement prior to re-paving. This meant the existing cracks would be exposed to the bottom of the  binder layer and would ultimately  reflect upward through the new pavement. The solution called for an inordinately crack resistant and resilient binder layer that either needed to be custom-designed, or an expensive two-dimensional geosynthetic rolled interlayer product.

“As a member of Surface-Tech’s Technical Advisory Committee, Phil is well versed on the capabilities of ACE XP, and he set about designing a completely new binder layer asphalt mix using it.”

Blankenship was able to deliver a design that Haydon could produce in its plant and pave with existing paving equipment. Using ACE XP in the new binder layer design gave Haydon Materials an effective crack resistant solution, while maintaining cost control for this demanding application.

The customized ACE XP mix achieved a new level of flexibility for the binder layer. The new binder layer design — a finely graded, highly asphalted crack resistant mixture — greatly reduced the potential for cracks to reflect upward from the base through the new pavement.

An  ACE XP reinforced surface mix was also designed utilizing a higher-than-normal asphalt content to provide even greater crack resistance than a typical FAA asphalt mix design,

“The development of this unique combination of mix designs for the binder and surface layer is an exciting advancement for the paving industry that holds great promise for dramatically improving crack prevention,” said Dennis.

“With this new approach, contractors can also control the quality in both production and installation, as the new mix design is simply incorporated into the contractor’s production processes, thus eliminating third party contractors to install the 2-dimentional geosynthetic rolled interlayer product.”

ACE XP aramid polymer fiber additiveAll require strength, flexibility and abrasion tolerance to achieve high performance. The common ingredient that delivers those winning traits is aramid fibers. These polymer synthetic fibers provide advantages that make them ideal for a wide range of products. So it’s not surprising that more than 60,000 tons of aramid fibers are produced annually, and demand continues to grow as new applications emerge.

Years ago, Surface Tech recognized the superior advantages that aramid fibers, particularly para-aramid fibers, could provide to asphalt applications. The company began offering the ACE XP aramid polymer fiber additive after years of painstaking research and multi-geographical testing. Back then, the challenge was to find a way to harness millions of tiny fibers into a final product that could be easily managed. By combining para-aramid with a wax treatment, Surface Tech achieved its goal of creating an additive that successfully reinforces and properly doses the entire matrix of asphalt.

The wax binds the polymer fibers to allow for an easy, reliable method for feeding into the asphalt mix. Once added, the wax melts and is fully soluble within the mix to release the polymer fibers in a uniform distribution. This unique delivery process produces the highest performing blend of Fiber Reinforced Asphalt Concrete (FRAC) on the market, and any asphalt project can benefit from ACE XP.

If you want an asphalt surface that resists cracking and rutting and dramatically extends the life of your pavement, call us. With para-aramid fibers, you’ll get asphalt that’s stronger than steel, and only from ACE XP — the Number One choice for strength, flexibility and abrasion tolerance.

ACE XP Polymer Fiber for asphalt

Contractors have come to depend on ACE XP Polymer Fiber from Surface Tech to make asphalt more durable and long-lasting. How does this high-tech additive deliver on its promise to produce extreme performance asphalt? The key lies in its chemical makeup — it’s composed of aramid polymers.

Aramid polymers contain a set of chemical properties that give them outstanding strength, flexibility and abrasion tolerance. They’re particularly useful in applications where flexing tolerance is important, like armor, airplane wings, ropes, cables, undersea pipelines, and of course asphalt applications.

To create ACE XP, high-strength aramid fibers are bundled and coated with wax to produce an asphalt additive that is simple and dependable to mix with any WMA or HMA in both drum and batch operations.  In fact, this binder use insures proper aramid delivery into the WMA/HMA; and coupled with our precise dosing equipment, delivers consistently intended amounts into every ton of asphalt.

One of the most outstanding performance benefits of ACE XP lies in its micro roots. These tendrils tenaciously anchor themselves into the bitumen of the asphalt, providing 400,000 psi tensile strength. The result is a three-dimensional reinforcement throughout the asphalt and a flexibility that resists rutting during hot summers and cracking through cold winters.

Contractors will also appreciate the fact that ACE XP is a “dry” polymer fiber. Comparatively, it’s less expensive, more reliable, and easier to adopt. The MD3+ dosing system from Surface Tech delivers an easy, foolproof way to add ACE XP to any asphalt mixture.

Yet the ultimate beauty to ACE XP is its scalability and batch-to-batch reliability. Combined with the life-span improvements it provides, it’s a winning way to armor your asphalt for the long haul. That kind of reliability allows contractors to sell and place with confidence, knowing the asphalt they provide will deliver extreme performance based on an excellent polymer.
